Patented July v28, 1931 UNITED STATES PATENT OFFICE' FRANK COMPANY `OIF SEATTLE, WASHINGTON CABIN vENTILafron Application led January 6, 1,930. Serial No. 418,964.

This invention relates to im rovements in ventilators and more especial y to va ventilator adapted for use in airplanes of the cabin typ- 'The principal object of the invention is Ito provide a ventilatorof this character which is of light weight, durable and inexpensive construction,y andl which can be readily mounted in the slde walls of the cabin lo at points within convenient reach of the ocproved form of ventilator in on the line 3--3 of 3D Referring now more particularly tothe 4a the ventilator is cupants or passengers.

These and other objects will appear as my invention is more fully hereinafter described in the following speclication, illustra-ted in the accompanying drawings and nally pointed out in the appended claims.

In the drawings: Figure 1 is a sectional end elevation of a conventional airplane cabin, showing my im- Qperative ena ement therewith. f

igure 2 is an enlarged front elevation of the ventilator, partly 1n section.

Figure 3 is a sectional side elevation Figure 2.

F 1 re 4 is a sectional end elevation taken on the line 4-4 of Figure 2.

Figure 5 is an enlarged detail view of an adjustable locking means.

taken 'drawingsz Y Reference numeral 1 indicates, generally,

' the cabin of an airplane, having a roof 2," sidewalls 3 and oor 4. The interior of the 5 cabin is provided with the usual seats 5 as shown.

My improved type of ventilator .is generally indicated at 6 and is mounted in the walls of the cabin.l The main body or frame 7 of of box-like formation and is secured to, and extends through, the side walls of the cabin. and extending beyond it, is a grooved frame 8 which is secured to the inter1or of the cabin 5 wall. Within the grooved frame is slidably mounted a door 9, which is provided with a knob .10 mounted to a spring 11 which is formed with a stud 12 or other-suitable projection. An apertured bracket 13 extends '5o transversely o the frame 7 and is secured to 'on the opposite side of Surrounding the frame 7 l 'ing swinging its side walls by mea-ns of abolt 14. The apertures 15 in the bracket are in the path of movement ofthe spring 11 as it-moves with the door 9 vin o ening or closing so that by pulling out'war ly on the knob 10 the stud 12 will become disengaged `from .the apertured bracket and the door 1s then free to slide in either direction. Upon releasing the knob, the stud will of course re-engage with the apertures and hold the door in any desired position.

On the vopposite or outboardside of the frame 7, a scoop shaped ldoor 16 is hingedly mounted as at 17. A link 1S connects the leading edge of the door 16 with the sliding door 9 so that as the sliding door is opened on the inside of the cabin, the door 16 on the outside will also open. The degree of opening of the outer door can be determined by the amount of opening of the inner door.

The outboard side of the frame 7 is provided with a plurality of bale plates indicated at 19 into the cabin when prevent rain, etc., from entering.

While I have shown a particular form of embodiment of my invention, 'I am aware that many minor changes therein will readilv sugest themselves without departing from the spirit and scope of my invention. Having thus' described my invention, what I claim as new and desire to protect by 1. In' a the combination'of swingably mount-ed by one edge at one side of said lframe member, another door mounted Letters Patents is t ventilator of the Iclass described,

sliding movement in opening away from the hinged edge of the other door, and, means interconnecting both of said doors for impartmotion to one door upon sliding the other of said doors.

2.' In a ventilator of the class described, the combination of a frame member, a sliding door on one-side ofsaid frame and a swinging door hinged by one edge at the'opposite side of said frame', the sliding door moving in opening away from the hinged edge of the swinging door, and a. link extending from the which allow free passage of air both doors are open but a frame member, a door said frame member iny to others skilled in t eart swinging edlge of the swinging door back towards its inge to a connection with the sliding door, to impart swinging motion to the swinging door upon movement of the slid-l ing door.- Y
